Autism Diagnostic Observation Schedule (ADOS) is one of the most popular instruments used world-widely in the diagnosis of autism spectrum disorders (ASD). Unfortunately, there are only a few studies of the psychometric properties of non-English language versions of this instrument and none of the adaptation of its second edition (ADOS-2). The objective of this study was to verify the psychometric properties of the Polish version of the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2-PL). The authors recruited 401 participants: 193 with ASDs (ASD group) and 78 with non-spectrum disorders, plus 130 typically developing participants (control group). ADOS-2-PL was found to have high interrater reliability, internal consistency and test-retest reliability. Confirmatory factor analysis confirmed a good fit of the Polish data to the two-factor model of ADOS-2. As no significant differences were found between participants with childhood autism and other ASDs, only one cut-off was established for Modules 1-4. The sensitivity, specificity and positive predictive value of ADOS-2-PL are high: sensitivity was over 90% (only for the "Older with some words" algorithm in the Toddler Module the sensitivity was 71% and "Aged 5 years or older" algorithm in Module 2 sensitivity was 84%), specificity was above 80% (with the exception of the Module 4 and Module 2 "Aged 5 years or older" algorithm where it was above 70%). The results support the use of ADOS-2-PL in clinical practice and scientific research. To the best of our knowledge, there have been no reports to date about adaptations of ADOS-2 and the psychometric properties of non-English language versions. As such, this constitutes the first attempt at adapting ADOS-2, and its results could be of interest for researchers outside of Poland.
《自闭症诊断观察量表》（ADOS）是全球范围内用于诊断自闭症谱系障碍（ASD）最常用的工具之一。遗憾的是，关于该工具非英语版本心理测量特性的研究较少，且尚无对其第二版（ADOS - 2）进行改编的研究。本研究的目的是验证波兰语版《自闭症诊断观察量表第二版》（ADOS - 2 - PL）的心理测量特性。作者招募了401名参与者：193名患有自闭症谱系障碍（自闭症谱系障碍组）、78名患有非谱系障碍者以及130名发育正常的参与者（对照组）。结果发现，ADOS - 2 - PL具有较高的评分者间信度、内部一致性和重测信度。验证性因素分析证实波兰数据与ADOS - 2的双因素模型拟合良好。由于在儿童自闭症患者和其他自闭症谱系障碍患者之间未发现显著差异，因此仅为模块1 - 4设定了一个临界值。ADOS - 2 - PL的敏感性、特异性和阳性预测值较高：敏感性超过90%（仅幼儿模块中“会说一些话的大龄儿童”算法的敏感性为71%，模块2中“5岁及以上”算法的敏感性为84%），特异性高于80%（模块4和模块2中“5岁及以上”算法除外，其特异性高于70%）。研究结果支持在临床实践和科研中使用ADOS - 2 - PL。据我们所知，迄今为止尚无关于ADOS - 2改编及非英语版本心理测量特性的报告。因此，这是首次对ADOS - 2进行改编的尝试，其结果可能会引起波兰以外研究人员的兴趣。
